HAIR-WAVING DEVICE.

Application filed June so, 1923. Serial No. 648,822.

To all whom it may com-em.

Be it known that I, HARRY JACOBS, a citizen of the United States, and a resident of the city, county, and State of New York, have invented certain new and .useful Improvements in Hair-Waving Devices, of which the following is a speclfication.

In producing what is generally called the permanent wave in the human hair it has been customary to wind each lock of hair around a rod or. curler, to place .a chemical agent or borax on or around the lock of hair or inside the curler and to place the curler and hair inside a tube which was subjected to heat either by means of an electric heater placed over the tube .or else by a circulation of heated air through the tube, the latter method being disclosed in various atents issued to Hannah Jacobs and mysel The lock of hair was moistened unless the chemical was in liquid form.

In prior methods it has also been customary to place a hinged shield around the lock of hair between the tube and the head in order to protect the head from excessive heat. But these shields are made in two parts and an opening must necessarily result. Notwithstanding the use of the shield there have been many cases where customers have been burned and this has resulted in expensive litigation. I have found that this burning is due not so much to radiated heat reaching the scalp as it is to the condensation of the vapors into liquid which passes through or around the shield and onto the scalp. As there is moisture in the tube when the process of waving is commenced, which is vaporized in the process of baking the hair, this vapor condenses as it cools and this is precipitated in the form of liquid which as above Stated, often came into contact with the scalp and caused burns. The object of the present invention is to avoid this objection and for this purpose I p-rovide a tube for wavin which can be used close up to the head, ut which will have a small drip chamber to receive and hold any precipitated liquid and prevent it reachin the scalp regardless of the angle of the tu e in relation to the head. This is accomplished with a device which may be handled with as much dispatch as any previous device and the present device is simple and compact. Other advantages will appear from the following detailed description of my invention.

In the drawings forming part of this application,

Figure 1 is a side elevation of one form of my device, showing it in use for waving.

Flgure 2 is anelevation, partly in section, of the inner tube and partially withdrawn from the tube;

Figure 3 is a longitudinal sectional view of the device, showing the outer member of the tube moved back as when the inner tube and curler are being inserted,

Figure 4 is a sectional view taken on the line 44 of Figure 3,

Figure 5 is a view similar to Figure 3 but with the device closed,

Figure 6 isa perspective view of one of the telescoping members of the tube,

Figure 7 is a longitudinal sectional view of a modified form of my invention,

Figure 8 is a detail view of one end of.

curler, with the latter member-to move therein. This outer memher is cut away at 6 to clear a connecting tube 7 and to permit the end 8 to extend down close to the end of the inner tube member 2. There is a long bayonet slot 9 in the member 3, in which a pinlO on the member 2 engages to limit the telescoping movement of the tube members and to hold them in closed position.

The inner tube member 2 has an end wall 11 near the head with a chamber 12 formed at its inner surface by the surrounding wall 13. This chamber receives any drops of liquid precipitated as a result of the condensation of vapors formed in the device. I prefer to provide a cork or other insulating cap 14 which may be cemented to the outer surface of the end wall 11 to prevent the metal coming in contact with the head.

The inner member 2 has another end wall 15, so that any vapors evolved in this member must pass out through the opening 16 in this member. The outer member has a slot 17 which when the two members are in closed relation, registers with one end of the opening 16 of theinner member 2, thus providing a vent for the discharge of hot air or, vapors at a point remote from the head.

The lock of hair is wound tightly about a rod or curler 18 which may be any form of curler usedfor such purpose, and in the form'here shown, the lock of hair is held upon the curler by a spring or bow 19, hinged to the curler. It is optional whether the curler and hair are inserted in this manner in the heating tube or whether an inner tube is used. But I prefer to insert the curler with the lock of hair wound upon it in an inner tube 20, which I have shown as closed at one end with a removable cork 21 whereby this tube may be left open or closed at its outer end. I

The tube 7 is attached along one side of the member 2 and one end opens into this member 2 while to the other end is attached a flexible hose or tube 22 which receives a ,-current of heated air from a suitable apparatus such as that shown in my U. S. patent. The operation of this form of my device is as follows :-Assuming that a lock of hair has been wound upon the curler 18 and that the curler and hair have been placed in the inner tube 20 (the use of this tube being optional) these are inserted into the inner heating tube member 2 through the opening 16 while the outer member 3 is slid out as shown in Figure 3 to leave this opening 16 open. This may be done while the device-is held close to the head, so that the hair may be wound on the curler as close to the head as in former practice. When the curler and hair have been inserted into the member 2, the member 3 is then telescoped along the member 2 untilthe two form a chamber 4. which is completely closed at the end nearest the head with the exception of the slight separation where the hair passes between the edge 8 and the edge 23.

Hot air is admitted through the tube 22 into the member 7, and from there it passes into the inner member 2, where it circulates around and into the tube 20, heating the lock of hair. This current of air passes along in the chamber 4: and discharges through the vent. It will be noted that the hot air first comes into contact with that part of the hair which is nearest the head which is also the thicker part of the hair and it requires the greatest heat, and that it then passes over the thinner portions of the hair after some of the heat has been given up. This action results in proper heating of the hair. It will be understood that moisture is applied to the hair before the baking operation commences and that the hot air causes this moisture to vaporize. The greater part of this moisture passes off with the current of heated air and out through the vent, but

there is generally a slight precipitation at the end of the heating tube nearest the head. With the present device, when this precipiare often in perpendicular position and ifthe drops were to discharge from the end of the heating tube they would reach the scalp. With the present device however, these drops simply collect in the chamber 12 and remain there until the baking process has been completed and the device is removed.

At any time during the baking operation, the operator may slide the outer member 3 along to expose a portion of the lock of hair to observe whether the process has been carried far enough. IVhen the baking is complete, the member 8, is simply slid along to uncover the opening 16 and the curler and hair are removed.

It will be apparent that the present device instead of being heated by a current of hot air in the manner shown may be heated electrically. In that case, any standard electric heater may be slid over the heating tube, as in former practice.

However for such purposes a device like that shown in Figures 7, 8 and 9 may be used. In this arrangement tubes now in use may be utilized with my invention. Herein I have shown a tube 24, of cylindrical form, which may have a flange 25 at the end nearest the head. The flanged end of this tube is closed by means of a removable cap 26 cork or other heat insulating material. In this device the curler with the lock of hair wound thereon, and the inner tube 20, if one is used, are inserted endwise into the tube 24 from the flanged end, and then the cap 26 is placed over the inner end of the tube 24, as shown in Figure 7. This form of device is especially useful in conjunction with the present forms of electric heaters as the latter may be simply slipped over the tube 24 and used in the same manner as heretofore. In fact, the tube 24: may be the same tube that is used in present practice but with the additional features here described.

From the above it will be apparent that I have provided a heating tube which will retain and hold any drops of liquid caused by precipitation of vapors and prevent these drops from coming in contact with the scalp regardless of the angle or position of the The cap may also be provided with a cover 29 of waving device on the head. 7 The device may be placed perpendicular or at any other convenient angle.

Having described my invention, what I claim is 1. A permanent waving device comprising a tube composed of telescoping sections,

the inner section having a chamber at the end lying adjacent the head, said inner tube having a side opening to receive therein a curler having a lock of hair wound thereon, and said outer tube section being adapted to slide over said side opening of said inner tube section.

2. A permanent waving device comprisinga tube composed of telescoping sections, the inner section having a chamber at the end lying adjacent the head, said inner tube having a side opening to receive therein a curler having a lock of hair wound thereon, said outer tube section being adapted to slide over said side opening of said inner tube section, and having a slot adapted to register with said side opening.

3. A ermanent' waving device comprising a tu e composed of telescoping sections, the inner section having closed ends and having a side opening spaced from the end nearest the head to form a chamber for holding liquid caused by condensation of vapors in said tube and said outer tube section being adapted to slide over the side opening of head, said first tube having an air outlet opening remote from the head.
